The Lowdown
Hey, Rusty here, lookin' at what's on the cards for the region. Gotta be honest, the start of the period is a bit of a write-off. There's a real quiet spell from now until Wednesday morning, with nothing worth paddling out for. The first hint of life comes Thursday morning, and that's where our focus will be.
Thursday the 3rd of September is the first real chance to wet a line. Jaconé is the spot, and early doors it's looking tidy. We've got a 5.6ft south swell, with a clean 10-second period, coming in under a clear sky and a moderate offshore breeze from the ENE. That means clean, lined-up waves with the wind holding the faces open. The combined energy is solid, in the moderate range (588), so there's a bit of push behind it. Water temp is about average for this time of year, so no shocks there. This is the standout of the early part. The afternoon holds up too, with a 5.2ft south swell, but the wind swings cross-off and picks up to 30 km/h, making it a bit more of a handful but still surfable.
Friday the 4th of September is another good one, maybe even cleaner. A 3.6ft SSE groundswell with an 11-second period, and the morning is dead glassy with barely a breath of wind from the north. That's a major positive. Expect clean, glassy conditions and consistent little lines. The swell energy is moderate (357). There's potential for crowds at Jaconé, as it "sometimes" gets busy, but on a morning like this, it'll be worth the company.
After that, we hit another patch of ordinary conditions. The weekend and early next week are small and not worth a mention, with winds all over the shop.
Now, look ahead to Monday the 7th of September. We get a jump in size with an 8.2ft south swell, but there's a catch. The period is 11 seconds, but it's a cross-shore wind from the SE at 15 km/h, creating some cross-chop. The wave energy hits a strong level (2191). This is big, powerful surf—definitely for experienced surfers only. Not a day for the beginners.
For the true standouts of the whole period, you have to circle Tuesday the 8th of September. Morning shows a 6.9ft south groundswell with a 12-second period. The combined energy is very strong (1255). What seals the deal is the clean conditions with a cross-offshore breeze from the ESE at 15 km/h. The afternoon is even bigger at 7.9ft from the SSE, with the same period and clean wind. This is excellent surf for experienced surfers. This is the pick of the bunch, no question.
A couple of other spots pop later. Thursday the 10th stays blown out by a fresh offshore, and Friday the 11th offers a return to clean conditions with a 5.9ft east swell and a consistent offshore breeze. That's a good option for a cleaner wave after the bigger days. Later, on Sunday the 13th, there's a clean 4.3ft SSW groundswell with a longer 12-second period. Good shape, but the big swell rolls in that afternoon with onshore wind, so get your session in early.
The very end of the run, around the 15th and 16th, fades back to smaller, cleaner surf but nothing to write home about after that main event.
So, to sum it up: Thursday morning is your gentle opener, but the big show is Tuesday the 8th. That's the day to lock in if you've got the skills for a 7ft+ groundswell.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Jacone is 14 km (9 miles) from the city of Saquarema. If you plan a holiday in Rio de Janeiro, look for hotels and other accommodation in Saquarema. Saquarema has rooms for a wide range of budgets as well as car hire and transport links.
